Jon Kinney e863cdb801 macos: refresh display bounds on reconfiguration ...

InputCaptureState fetches the active-display bounds once in new()
via CGDisplay::active_displays(), and crossed() / start_capture()
both consult those frozen bounds for every barrier check and
cursor warp. Plug in a monitor, change resolution, or rearrange
displays in System Settings and the bounds go stale immediately:
the cursor either stops crossing at the new edge or warps to the
old edge coordinates.

Register a Quartz CGDisplayRegisterReconfigurationCallback on the
event-tap thread's CFRunLoop and route a new
ProducerEvent::DisplayReconfigured into the existing producer
channel. The producer task re-runs update_bounds() on the live
state, so subsequent barrier checks use the current geometry.

The callback fires twice per change — once with the
kCGDisplayBeginConfigurationFlag (BEFORE the bounds update) and
once after — we filter the begin-phase out and only refresh on
the post-change notification. The callback registration is
removed and the leaked sender Box is reclaimed when the run loop
exits, so create/destroy cycles don't leak channel senders.
